Victorians are notorious for having NO closets (they used armoires).
Sez me - recovering old house victim (1900 story and a half victorian in Washington Park).
Tip - skip the popular mechanics home repair manuals - they only cover modern construction. Get old-house specific repair books and when hiring tradesmen hire old guys who remember how that stuff was put together. Young guys just want to rip everything out and do it over (kind of like programmers that way).
Otherwise - hey congrats! I loved my old house - you're never hurting for something to do on a weekend.
